Manufacturing Quality Control of 4,6-DICHLORO-2-(METHYLTHIO)PYRIMIDINE-5-CARBOXYLIC ACID
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at 254 nm. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC with UV detection; identification based on retention time matching and threshold limits per ICH Q3A/B. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents (e.g., methanol, acetone, DMF) against calibrated standards. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine trace water content via stoichiometric reaction. |
| Heavy Metals | ICP-MS | Quantitative determination of elemental impurities (e.g., Pb, Cd, As, Hg) after acid digestion, using inductively coupled plasma mass spectrometry for sub-ppb sensitivity. |
| Chloride Content | Potentiometric Titration | Titration with silver nitrate using a silver indicator electrode; endpoint detected by potential change due to AgCl precipitation. |
| Sulfur Content (as thiol) | Oxidative Combustion followed by Ion Chromatography | Complete oxidation of sulfur to sulfate, followed by anion exchange chromatography with conductivity detection. |
| Residue on Ignition | Gravimetric Analysis | Heating sample at 700-800 C to constant weight; residue measured as inorganic ash content. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity patterns to determine volumetric particle size distribution in dry or wet dispersion. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, using calibrated capillary apparatus per USP <741>. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through a solution, indicating chiral purity or absence of enantiomeric impurities. |
| pH of Aqueous Suspension | pH Meter | Measurement of hydrogen ion activity in a defined aqueous suspension (e.g., 1% w/v) using a calibrated glass electrode pH meter. |
